I spotted a new UV LED bulb at the "orange" DIY store tonight so I picked one up.
The bulb is rated at 9w and has an array of 26 SMT LEDs under a semi-transparent plastic dome. I fired it up and found that it appears to have a shorter wavelength than the standard purple NUV LEDs, which is good. However the plastic dome seems to fluoresce a little bit, slightly reducing the contrast of the UV effect, so I'm considering removing it.
Not a bad little bulb for $15. It will come in handy for Halloween, and I can probably also use it as a diazo exposure lamp for my screen printing setup.
**Update**
I aimed another UV lamp into the globe on this bulb to see what is fluorescing, and it's not the globe; it's the white plastic bodies of the UV LEDs themselves.
